Can 2wd Tundra handle 37's

[eurobro]

I have the rcd 6'' and 35's now and I am so dissapointed. I love my truck to death but want it taller/bigger. Im not one for offroad performance im more of the mud poser guy that you would laugh and say "haha hes only 2wd" ....doesnt bother me.

So anyhow I am dying at ideas of getting more lift and maybe throwin on some 37's when these 35's take a poop. I have talked to many many people about doing a body lift on my 2006 and have heard mixed responses. Some people say there is no problem with them at all and some say they wouldnt ever do it again it ruins your body of your truck. Well I am willing to chance it since so many others on this site run with a 3'' body lift on there trucks. My main question would be that if I installed a 3'' BL which would = 9'' of lift on my dbl cab I would def. throw on 37's since IMO the 35's would be a lil on the small side.

Would 37's tear the front end of my truck up? Would it eat away at balljoints to the point where it would be in the shop every year getting everything replaced? I want to do this whole 3'' BL and 37's but do not want to ruin the truck. Like I said I just pound pavement only. Any info would be greatly appreciated. Thanks, Derek.

you can run 37s. Go to Cardomain.com there are a few around.

you bought your tundra in Brandon? I am in tampa... where did you get the RCD done at? I want RCD and 35s somethin fierce! LOL

Keep Juggling Derek.

I have seen a few trucks with body lifts with no issues.

Yeah a 9" lift will fit 37s depending on what size wheel you have.

Yeah, it will tear stuff up faster, there is no question to this, but it won't likely be every year just being a pavement pounder.

Get the Gap guards if you do the body lift.

Heck if you want to go huge, get the IVDs and some custom Alcan rear springs to give you 7" in the front and 5" in the rear then get a 3" body lift and roll 10" high with 37s or 38s. If you aren't using it like a truck then hell with it, it's only money, right!?!?!?

Yes bought it in Brandon Tampa. I am from Melbourne/Palm Bay area. I brought the lift offline and put it on myself. PM me for any other questions.

But that didnt answer my question to the fullest. I know you could run 37's but as far a reliability and long term effects like previously stated. Thnx!

[eurobro]

Thnx IMdone your always there. Im so tossed up on what im going to do. Gotta spend money to look good.

Anyone else have any input on this?

[Tundrav8yamaha]

my friend 2nd gen Tundra has them (37)..Biggest first gen I've seen is Mikes Tundra (tundraon42) and his truck had 42 inch wheel's thus I would think 37 would be fine with the right mod's and money $$$$.

the affects are the same as if on 4x4... of course bigger tires will cause more stress over time but 2wd will hold up just as well. Beside the difference between 37s and 35s (weight wise) isn't that much

[DevinSixtySeven]

There is a huge difference between 35s and 37s.

The most wear will likely be inner tie rod ends, upper ball joints, and bearings, since there's much more leverage applied.

37s might seem like they're just a tiny step up from 35s, that's not the case at all.

The engine, even with headers, chip, and 4.88 gears at the axle, will work a lot harder to turn them and keep them turning on long, steep hills.

Ackerman angle isn't quite as accurate with 37s as with 35s, mainly due to the often greater section width, and need for a wider wheel or less backspacing. This also affects scrub radius, which makes the truck harder to maneuver in tight spaces...it almost has to be rolling, if only slightly.

A 37x12.5R17 tire can easily weigh 70#, plus a 25#-35# wheel...mine weigh in around 110-115# per corner with aluminum wheels, and it is very noticeable under acceleration as well as braking.

Tire pressure becomes even more important, since you'll be running on an even larger air spring than before.

Be wary of running offroad. You should be fine on the beach, on dirt roads and mellow doubletrack (all 2WD territory). The rear axle is strong, but don't push your luck...get spinning with those tires, on or offroad, and you're asking for carnage.

You'll still be able to break them loose around corners, and occasionally one wheel from a standstill. Avoid this unless you've built the rear end.

You'll be fine if you keep all the above in mind.

I've been running 37s off and on since sometime last fall, and plan to run them as snow tires. Would run 38.5s as snow tires but I don't think they'll fit without a wider rim and a lot more trimming, and the Arctic Trucks guys had a spindle bending with their 38x15R15 tires on a 2nd-gen Tacoma.

FWIW I do run 35s for harder offroad routes. The 37s are for easy stuff...that's just the way it has to be, since the IFS drivetrain isn't built to handle 37s, but that's nothing to do with the steering or suspension I'm running. Yup, it should be the other way 'round.

Thank you Devin that is exactly what I wanted to hear. The biggest problem I could think of with them is braking, the 33's made a difference and the 35's made it even worse and I can only imagine 37's coming to a quick stop. I am a careful driver anyhow. Thanks again.

[Imdone]

For braking, you can either spend the big bucks on the TRD big brake kit or you can get a set of powerslot or powerstop drilled and slotted rotors and harder pads and that will help a little more. I had power slots and hawk pads on my 00 and running 35s it helped.

[eurobro]

Will those TRD big brake kit work with 16'' wheels? I have the AR Mojave's.

[TundraSurfBum]

I went from 35s to 37s BFGs and notice no difference what soever (jeep TJ) I didn't even have to regear... as for angles I guess I can't speak for the Tundra, but with the Jeep the suspension is what dictated angles... not tires

[DevinSixtySeven]

How many Jeeps do you know with a GVW slightly over three tons?

How many Jeeps, other than those with Corvette engines, are capable of easily running 100mph?

How many Tundras do you know which are geared like a Jeep?

Trust me, you can hit triple digits on 37s in the Tundra, even when it weighs 6000#, as my truck does on a daily basis. With 4.88 gears and 37s, it's slightly overgeared...but close enough that it'll run hard and fast, and there's very little transmission brake when you let off the gas, even at that speed.

A Jeep and a Tundra are two completely different animals...everything about them is different.

Keep in mind too that our braking system in the rear was taken from a Tacoma, and in front was identified by Toyota as requiring a TSB and redesign. Believe me when I say you'll notice the 37s.

You will need to upgrade your brakes somehow if you want anything close to stock performance, and it'll still be sub-par unless you rework the entire system. I've been running upgraded rotors and pads for years now, and I still notice a difference going from the 35s to the 37s (I keep two sets of wheels & tires).

The BBK is a balanced kit...meant to integrate seamlessly with the existing system. It would be a lot better to jump to a completely different system.

Your best bet, if you want to improve the performance, is plan for a 17" or 18" wheel, plan to convert your booster to double diaphragm and master cylinder to 1" bore or larger (ours are 13/16"), and talk to a company like Revolution about getting front and rear rotors and calipers appropriate to your weight distribution and new master cylinder size. They can do it, but you'll need larger rims.

There are a few companies that make 37" tires for 17" & 18" rims...I think all the "boutique" manufacturers do it, plus BFG and Interco.

No, it ain't cheap...none of it is. You could also try a narrow tire, it'll be lighter than the bro-show tires which means it'll be easier to start and stop, and you may find it'll fit vs a wider tire. A 38.5x11.0 Bogger only weighs 69#, it'll weigh less when you're done cutting it (highly recommended by everyone who runs Boggers), and it'll work on your 16x8 rims...that should keep the weight under 100#. BTW it measures to 38" diameter, which is spot-on for 4.88 gears.

Minimum 17s

[eurobro]

I'm keeping my wheels so any brake plans that need bigger are out and do not plan on adding anything serious to the brakes like what you mentioned.. I would however like to get better rotors/pads for the next brake job though. As for the rear is there Sequoia brakes that can fit on our Tundra's for better stopping ability?
